    Weight in the charge on the scant side (I usually omit the suction line), then come back once temps are more appropriate. Fieldpiece has a charging blanket that will help with cooler outdoor temps, but without a load indoors too you're still just guessing.

    Some units (min splits & VRF/VFF) are only ever charged by weight—they can be charged in any weather.

    There is no Ambient temperature, Method!

    Reach ins will have a tag showing the total charge.

    Heat Pumps will also have a tag but to have to account for the line set length and add or subtract.
